This is like the 4 World Supercomputers at the end of Asimov’s I, Robot. Humans do all the work (industry, agriculture, economy, etc) and then feed the data into the computers who orchestrate/tell humans what to do.

But "AI" already does drive the tractor/combine/sprayer etc.

Look up precision ag.

You can lease 5 acres in Iowa for $1370? Per month I guess? In which case it will be $1370 * m. Not clear from here: https://proofofcorn.com/

A quick search of actual data shows that farmland suitable for row crops sells for ~$11k per acre so a 5 acre area would be around $55k. If the market rate for that type of land was $1,370 per month, that comes to a rate of return near 30% yearly (assuming leases are yearly, not seasonal)![0]

I dug a little deeper and found this study showing cash rental rates per acre per year ranging from $215 to $295.[1] So it actually looks like Claude got this one right.

Of course I know nothing about renting farmland, but if you ask to rent 5 acres the average farm size is in 300+ acre region, the land owners might tell you to get lost or pony up. A little bit like asking Amazon to give you enterprise rates for a single small EC2 instance.

Really cool - even cooler if some farming related hardware on a designated plot of land can be setup so it's more than an ai agent finding someone to hire via apis.

Given how the front page's ASCII diagram is misaligned on my browser, I think I have a few concerns about factors that might lead to, well, oversights...

Ha! I was going to disagree, but then I realized I force most monospace html entities to use a specific font in my browser (using a wildcard stylus stylesheet). This is quite nice to normalize things (and sidestep atrocious font choices) actually.

Anyway, turned it off; sure enough, misaligned.

Reminds me of this project from friends of mine:

Interesting!

But where is the prompt or api calls to Claude? I can't see that in the repo

Or did Claude generate the code and repo too? And there is a separate project to run it

We, as in humans?
